Title: Control method of corona electrifier of electrophotographic device
Inventor: WATANABE TAKESHI
IPC: G03G15/02
Filed: 1984-03-09
Abstract: PURPOSE:To perform excellent electrostatic charging during image forming operation and eliminate the residue of ozone when the operation is stopped by grounding a conductive shield electrically through a stray or high resistance during the image forming operation, and grounding it directly or through a low resistance when the operation is not performed. CONSTITUTION:The conductive shield 12 is connected to the high resistance A during copying operation, so a shield potential is high and a corona wind flows in from an opening (a) in a shield back surface and flows out of the gap (b) between the shield 12 and a photosensitive drum 2. The corona wind flows toward the photosensitive drum 2, so the surface of the drum 2 is charged easily and held at an uniform potential. The conductive shield 12 is grounded B directly during rotation after the copying operation, so the shield potential is at ''0''V and the corona wind flows to the shield side to flow in from the gap (b) between the shield 12 and drum 2 and flows out of the shield opening (a), thereby removing ozone remaining in an electrifier.
